Smart soft starter MINISTART | UG 9256

asynchronous motorelectronicthree-phase

The smart motorstarter function is a softstart, reversal and protection of 3-phase asynchronous motors. Overcurrent is detected when the set current is exceeded longer than 2 sec. Direction reversal takes place via relay switching. The relays are de-energised at this. This ensures a long service life. Features • According to IEC/EN 60 947-4-2 • To reverse 3 phase motors from 90 W to 750 W resp. 550 W to 4 kW at AC 400 V • 2-phase softstart • Max. 4 potentiometer für setting of starting torque, deceleration torque, softstart /-stop, overcurrent limit or rated motor current • 4 LEDs for status indication • Reversing with relays without current, softstart, softstop with thyristor • Galvanic separated 24V-inputs for clockwise- and anticlockwise • Reset button on front • Connection facility for external reset button • Relay indicator output for operation • Indicator output at customers specification (on request) • Galvanic separation between control circuit and power circuit • Width: 22.5 mm Advantages / Customer benefit • Up to 6 function in one unit - Reversing anticlockwise - Reversing clockwise - Softstart - Softstop - Current monitoring or motor protection - Galvanic separation via forcibly guided contacts contact distance min. 0.5 mm • 80 % less space • Simple and time-saving commissioning as well as user-friendly operation through setting via potentiometers on absolute scales • Blocking protection • Hybrid relay combines benefits of relay technology with non-wearing semiconductor technology • High availablility by - Temperature monitoring of semiconductors - High withstand voltage up to 1500 V - Load free relay reversing function
